37 * This file implements a translation layer between the BSD networking
38 * infrasturcture and Windows(R) NDIS network driver modules. A Windows
39 * NDIS driver calls into several functions in the NDIS.SYS Windows
40 * kernel module and exports a table of functions designed to be called
41 * by the NDIS subsystem. Using the PE loader, we can patch our own
42 * versions of the NDIS routines into a given Windows driver module and
43 * convince the driver that it is in fact running on Windows.
44 *
45 * We provide a table of all our implemented NDIS routines which is patched
46 * into the driver object code. All our exported routines must use the
47 * _stdcall calling convention, since that's what the Windows object code
48 * expects.

2889 * list in search of those symbols and we've found the file
2890 * data. As an added bonus, ndiscvt(8) will also generate
2891 * a normal .o file which can be linked statically with
2892 * the kernel. This means that the symbols will actual reside
2893 * in the kernel's symbol table, but that doesn't matter to
